tbreak

This command sets an execution breakpoint at a specific location
and subsequently deletes it when the breakpoint is hit. You can
also specify a conditional breakpoint by using an if statement
that stops only when the conditional expression evaluates to true.

Note

Breakpoints that are set within a shared object are deleted
when the shared object is unloaded.

Use set breakpoint to control the automatic
breakpoint behavior when using this command.

Syntax

Specifies whether or not the resolution of an unrecognized
breakpoint location results in a pending breakpoint being created.

filename

Specifies the file.

location

Specifies the location:

line_num

is a line number

function

is a function name.

label

is a label name.

+offset | -offset

Specifies the line offset from the current location.

address

Specifies the address. This can be either an address
or an expression that evaluates to an address.

number

Specifies one or more threads or processors to apply
the breakpoint to. You can use $thread to refer
to the current thread. If number is
not specified then all threads are affected.

expression

Specifies an expression that is evaluated when the
breakpoint is hit.

If no arguments are specified then a breakpoint is set at
the current PC.

Example

Example 149. tbreak

tbreak *0x8000 # Set breakpoint at address 0x8000
tbreak *0x8000 thread $thread # Set breakpoint at address 0x8000 on
# current thread
tbreak *0x8000 thread 1 3 # Set breakpoint at address 0x8000 on
# threads 1 and 3
tbreak main # Set breakpoint at address of main()
tbreak SVC_Handler # Set breakpoint at address of label SVC_Handler
tbreak +1 # Set breakpoint at address of next source line
tbreak my_File.c:main # Set breakpoint at address of main() in my_File.c
tbreak my_File.c:8 # Set breakpoint at address of line 8 in my_File.c
tbreak function1 if x>0 # Set conditional breakpoint that stops when x>0
